A simple quantum simulation algorithm with near-optimal precision scaling
Amir Kalev, Itay Hen
Quantum simulation is a foundational application for quantum computers, projected to offer insights into complex quantum systems beyond the reach of classical computation. However,…

Feynman path integrals for discrete-variable systems: Walks on Hamiltonian graphs
Amir Kalev, Itay Hen
We propose a natural, parameter-free, discrete-variable formulation of Feynman path integrals. We show that for discrete-variable quantum systems, Feynman path integrals take the f…

Accounting for gauge symmetries in CHSH experiments
David H. Oaknin, Amir Kalev, Itay Hen
We re-examine the CHSH experiment, which we abstract here as a multi-round game played between two parties with each party reporting a single binary outcome at each round. We explo…
